New 75amp alternator..blew fusible link.

Awsome, thanks! So you replace the connector on the bulkhead connector it sounds like? It should be removable?

Also, should have mentioned, I'm running the FBO ignition system. The regulator is an electronic unit, just looks like the old mech. regulator, but if you pull the cover it's a circuit board in there, and the black ECU is FBO as well.

My worry is that I replace the fusible link, and the issue just happens again because my wire is so old (Original everywhere). Should I upgrade my alternator wire connections to thicker gauge?

Thanks again for the ECU connection answer too! I'll tape and conceal it better as long as it's connected correctly.

Thanks again!
